JOHN F. PENROD, OF BLAIRSVILLE lNTERSECTION, PENNSYLVANIA, AS- SIGNOR .OF ONE-HALF TO WILLIAM N. HAYES AND SIMON O. YOUNG,

RAILROAD-FROG.

SPECIFICATION forming part of Letters Patent No, 351,884, dated November 2, 1886. Application filed June 26, 1886. Serial No. 266,353. (No molel.)

To all whom it may concern:

Be it knownthat I, JOHN F. PEnRon, a citizen of the United States, residing at Blairsville Intersection, in the county of Westmore- I ticularly to the means'for permitting one train to pass from the side to the maintrack, or vice versa,without imparting any jolt to the cars or any beating down of the track. Heretoforeit 20 has been accomplished by what are commonly known as frogs; 7 but a gap was left betweentheintersecting rails, which caused a jolt to the cars and a beating down of the rails on each side of the gap. These difficulties have been 2 5 obviated by cutting away a portion of the'sides of the branch rails, so that their upper ends may overlap the main track, thus presenting a continuous rail for the siding. This has been found objectionable, because it throws an obstruction across the main track, which, if neglected, may cause the derailment of a train moving on the main track.

The object of my invention is to maintain a continuous rail practically on the main and side 3 tracks and allow of the cars passing over each other without any jolt or beating of the rails,

and to devise a simpleconstruction for effecting the same, and have the rails of the main and side tracks in the same plane at thepoint 0 of intersection.

The invention consists in having the wingrails ofa frog made yielding and normally held against the sides of the main rail, which is grooved the depth of the flange of the wheels, 5 as will more fully hereinafter appear, reference being had to the annexed drawings, in which- Figure 1 is a plan view of a section of track, showing my improvements adapted for side in the respective figures.

The main and side tracks, A and B, respectively, are of ordinary construction. The proximate rails intersect at apoint, b, and the main rail, forward of this point, is grooved to the depth of the flange of the wheel. This groove a 'extends parallel with the branch rail,-and

gives clearance for the flange of the wheel when crossing the main track, either when leaving or coming upon it. Lapped alongside the main rail are the yielding rails G, which are pivoted at one end close to the main rail, and the other ends are free to be ,moved to and from the 63 main rail, and are held normal by springs d on rods 01, which are located beneath the rails and between the ties. These springs, which may be either push or pull springs, yieldingly hold the rails 0 against the sides of the main 7o rail. There may be only one yielding rail 0, as shown in Fig.1, or two, as shown in Fig. 2.

In the former case it is designed for side track only, in the latter case for use in yard or at such'point where the cars are shifted to and fro.

It will be noticed that the second rail 0 employed in Fig. 2 is a continuation of one of the side-track rails. The ends of the rails O opposite the pivots are curved to one side to per-' mit the flanges of the wheels getting a purchase to force them aside.

In'practice the rails O fit close against the main rail opposite the groove to, and the treads of the wheels are snfficiently broad to extend beyond the main rail and fit a'pnrchase on the rails C, so that in going in any direction the tread of the wheel will have a continuous hearing, and when crossing the groove a will have a bearing upon the yielding rail. In Fig. 1 the dotted lines showthe position of the yielding o rail as it would be when a train would be moving-from the side track upon the main track.

D are brackets orstops secured to the ties, for limiting the outward movement of the rails O, and D are similar brackets for fixedly securing the guard-rails E in place.

The yielding rails may rest directly upon the ties or upon any suitable bed secured upon the ties, as desired.

The grooved rail may be Strengthened on 5 each side of the groove by fish-plates bolted to the web of the rail in any suitable manner, as will be readily comprehended.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

1. The combination, with the main and side track having the main rail grooved at the point of intersection, of a rail yieldinglyheld alongside the rail opposite the groove, substantially 15 as and for the purpose set forth.

2. The combination, with the main and side tracks having the main rail grooved at the point of intersection, of two rails embracing the grooved rail and lapped alongside and yieldingly held close thereto, substantially as and 20 for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN F. PENROD.
